First bolt the open end of the disconnects to the sway bar by using the bolt and nut supplied. You don't want to tighten these too much as this will bind up the sway bar. This is a good time to change the bushings in the end of the sway bar if yours are shot. Line up the lower bolt holes with the axlehousing mounts and use the old sway-bar bolts and washers. The Warrior Products disconnects come with polyurethane bushings installed.
